ASTM D2985\/D2985M-92-e1-Reapproved2011<\/h3>\n

Historical Standard: Standard Test Method for Color of Asbestos<\/h4>\n
\n

ASTM D2985\/D2985M<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of color, whiteness, and yellowness of asbestos by means of a photoelectric reflectometer.<\/p>\n

1.2 The test method is applicable to all grades and varieties of homogeneous milled asbestos.<\/p>\n

1.3 This test method may be applied to samples that are not dry or homogeneous, or that contain impurities or adulterants. However, in such cases, results may not be comparable with those obtained on clean dry samples.<\/p>\n

1.4 To obtain similar results from spectrophotometers, see Test Method E308.<\/p>\n

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.<\/p>\n

1.6 Warning\u2014<\/b>Breathing of asbestos dust is hazardous. Asbestos and asbestos products present demonstrated health risks for users and for those with whom they come into contact. In addition to other precautions, when working with asbestos-cement products, minimize the dust that results. For information on the safe use of chrysotile asbestos, refer to \u201c<\/span>Safe Use of Chrysotile: A Manual of Preventive and Control Measures.\u201d<\/span><\/p>\n

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span> ^REFERENCE:<\/p>\n
